I have been using the laundry strips and what i like about them the post is the packaging. Takes no space at all to store next to the laundry area, it is not heavy like jugs of detergent are and there is no wasted plastics. They come in a cardboard envelope and the strips are easy to tear a part. I use two for heavy use and one for lighter loads.
I hope to become an affiliate for TRUEARTH and will have this up and running soon.
